San Francisco Giants outfielder Jose Guillen, left off the team’s postseason roster, is linked to a federal investigation into shipments of performance-enhancing drugs, The New York Times reported on its website Thursday night.

The story, citing several unidentified lawyers, said federal authorities told Major League Baseball they were looking into shipments of human growth hormone, allegedly sent to Guillen’s wife in the Bay Area.

That was just before the postseason began, The Times said. Guillen was left off the Giants’ roster for all three rounds because of a nagging neck injury, according to manager Bruce Bochy.

A person in Major League Baseball confirmed the investigation to The Associated Press. The person spoke on condition of anonymity because the probe was ongoing.

“I don’t know anything about it and right now I don’t have a comment,” Bochy said.

Jay Reisinger, Guillen’s attorney, also declined comment in an e-mail. San Francisco beat the Texas Rangers 9-0 on Thursday night for a 2-0 lead in the World Series.

Guillen’s teammates were surprised to learn of the investigation.

“Hmmm, I never heard about it,” Eugenio Velez said. “Wow.”

Pablo Sandoval also had no knowledge of Guillen’s situation and would not comment.

Hitting coach Hensley Meulens said he hadn’t been in contact with Guillen since the playoffs began.

“I have no clue, no idea,” Meulens said upon being told of the investigation.
